Grizzly Bear
Identifying a Grizzly Bear
Color varies from blond to black. Often medium-to dark-brown legs, hump, and underparts with light-tipped (grizzled) fur on head and upper body.
Average weight is 500 pounds for males and 375 for females. Males may weigh up to 900 pounds.
Height is 3.5 – 4 feet at shoulder when on all fours, and 6 –7 feet when standing upright.
Distinctive shoulder hump is actually muscle mass that enables powerful digging.
A dished-in profile between eyes and end of snout helps distinguish grizzlies from black bears.
Ears are round and proportionately small.
Front claws are 2-4 inches long, slightly curved, and good for digging. Claw marks are usually visible in tracks.

Behavior

Usually more aggressive than black bears.
